FIREPROOF SECTIONAL CHIMNEY OR STACK.

SPECIFICATION forming part of Letters Patent No. 619,251, dated February7, 1899.

Application led March 5, 1898. Serial No. 672,649. (No model.)

To @ZZ whom t may concern:

Be it known that I, CHRISTOPHER S. Donn- MUs, a citizen of the UnitedStates, residing in Pequannock, county of Morris, and State of NewJersey, have invented certain new and useful Improvements in FireproofSectional Chimneys or Stacks; and I do hereby declare the following tobe a full, clear, and exact description ot' the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and toletters of reference marked thereon, which form a part of thisspecification.

The object of my present invention is to provide a sectional reproofchimney, preferably metallic and designed for dwellings or privatehouses, but which chimney can also be made applicable for factories,mills, the., or, if desired, can be used as an independent e-stack thechimney being of simple, strong, and durable construction, efficient inoperation, and can be quickly put up and occupies less space than anordinary chimney of the same capacity andA requirements.

The invention consists in the improved sectional fireproof chimney, inthe means for connecting its independent sections, and in thecombination and arrangement of the various parts, substantially as willbe hereinafter more fully described and finally embodied in the clausesof the claim.

Referring to the accompanying drawings, in which like letters ofreference indicate corresponding parts in each of the several views,Figure l is a front elevation of my improved chimney, partly in sectionand designed for a two-story basement dwelling; Fig. 2, a side elevationof the lower portion of Fig. 1; Fig. 3, a top plan view of a certainintervening hearth -plate corresponding to the hearthplate of the rstiioor; Fig. 4, a sectional view on the line c w of Fig. 1; Fig. 5, anenlarged detail view of a certain stovepipe receiver or thimble; andFig. 6 an enlarged detail view of a portion of one ofthe sections of thechimney, illustrating the means for keying mortar or othernon-conductive material to said section when desired or necessary.

The chimney illustrated in the drawings, as heretofore stated, isdesigned for a twostory basement dwelling and is placed in such a mannerthat it can be made use of from the apartments on either or both sidesthereof.

In said drawings, a represents the base- 5 5 ment-floor, b and c thefloors for the first and second stories, respectively, and CZ iheroof ofthe building.

On the basement-floor is arranged in any desired manner (preferablyembedded there- 6o in) a substantially rectangular-shaped bed orfoundation-plate e, provided near its outer edge with a groove orrecess, in which is arranged the correspondingly-shaped section f of thechimneyand which section contains the flues or ash-chutes f f2 formed bythe partitions f3 and f4. Each of said iiues is provided with a door f5,which can be opened for conveniently inserting an ash can or receptaclef6, iitting snugly in its respective flue 7o and preferablycommunicating with and below a hopper f7, arranged in and secured to thetop portion of the section f. The top portion of said section f isprovided with a langef8 and adjoining tapering groove f9, 75 Y adaptedto receive the correspondinglyshaped lower portion of the intermediatesection g, which is likewise provided with lues g g2 in alinement withthe tlues f and f2. On the top portion of the last-mentioned sec- 8otion g, which latter extends to about the firsttloor line, is placed thehearth-plate 7L, which for that purpose is provided on its under sidewith a groove corresponding in shape and dimensions to the groove in thebed or foundation-plate e and is further provided with openings t and h2in alinement with the lines g and g2. Within a groove in the top portionof said hearth-plate it is set the section z', preferably consisting oftwo (or more) sections t" 9o 712, jointed together in a mannersimilar tothat described in connection with the sections fand g. Said section 2'-,besides containing size stovepi pe, while the aperture itself is adaptedto receive the medium size, and the thimble 8, which is adapted to ttightly in said aperture and its annular groove, is designed to receivethe smallest size stovepipe, as will be manifest. Each of the iues 3 4is prvided with aidoor 711, hinged at its bottom and having on each sideprotector-plates 11. Said door, which naturally is constructed to closetightly the opening in its respective iiue, permits the dumping of theashes from the irst-floor stoves into the ash-can, while the dust andsmaller particles of the ashes are drawn up the chimney by the strongdraft produced within the ue by opening said door.

If desired, a mantel 1112 can be cast integral with its respectivesection, as illustrated in Figs. l and 2 of the drawings.

The section i extends to about the floorlne of the second story andsupports the hearth-plate fm, constructed substantially in the samemanner as the hearth-plate h and having additional passages lm' m forthe Iiues 5715. Said hearth-plate serves as a foundation for the sectionn, substantially the same in construction as the section i andpenetrating the roof d and carrying the top or cap o.

AIt must be remarked that the said section fn,

besides the iues in alinement with the lues 3 i4 '115 115 of the lowersection t', contains additional ues fn. 'n2 for the stoves in the secondstory. Y

The top or cap ois provided with a number of partitions forming flues orpassages communicating with the lines and ash-chutes in the section nand is jointed thereto in a manner similar to the joint heretoforedescribed in connection with the sections f and g.

On the top of the cap o is mounted in any desired manner a hood p, asclearly illustrated in Fig. l of the drawings.

At or near the top and bottom portion of each section and on oppositesides thereof are arranged and cast integral therewith projecting lugsq, adapted to receive the stud- .ding of the partitions to thusstrengthen the same and at the same time act as braces for said chimney.

The chimney may be painted or otherwise decorated, or, if desired, canbe surrounded by a layer of mortar or other non-conductive material,such as asbestos or cement. For that purpose the outer surfaces of thesections constituting the chimney are provided with a series of groovesor corrugations, (preferably dovetailed,) which latter permit of themortar being securely keyed to said section.

If desired, the flanges and tapering grooves of the various sections maybe coated Vwith asphaltum or other similar substances to insure a moreperfect joint, through which no sparks or ames can possibly escape.Y

I do not intend to limit myself to the precise construction shown anddescribed, as varions alterations can be made without changing the scopeof my invention; but
